Enable msix load balance only when combined reply queue mode is disabled on the SAS3 and above generation HBA devices. Earlier msix load balance used to enable if the number of online cpus is greater than the number of MSI-X vectors enabled on the HBA. Combined reply queue mode will be disabled only on those HBA which works in shared resources mode. I.e. on SAS3 HBAs it will be <= 8 and on SAS35 HBA devices it will be <= 16. - Before this patch if system has 256 logical CPUs and HBA exposes 128 MSI-X vectors, driver will enable msix load balance. - After this patch if system has 256 logical CPUs and HBA exposes 128 MSI-X vectors, driver will disable msix load balance. - After this patch if system has 256 logical CPUs and HBA exposes 16 MSI-X vectors (due to combined reply queue mode being off in HW), driver will enable msix load balance.
